2. site analysis & existing conditions 3. Lake, landform, & hydrology Lake Ellyn Park lies in the valley between Lake Road to the east, Glenbard West High School to the south, and a residential neighborhood to the west. The parkland slopes gently towards the lake from the east and the west. The Ruth Candy Parkway and Sam Perry Preserve are lower than the lake elevation (approximately 703 el.). The 10-acre Lake Ellyn is a manmade lake that serves as a regional stormwater detention facility for a 614-acre watershed that includes a significant portion of the Village of Glen Ellyn. Lake Ellyn was historically spring-fed, although its hydrology was altered as part of the Village’s stormwater management system. There are two inflow points at the south end of the lake, and an outflow at the north. Events greater than an approximately XX-year event rise above the banks and begin to spill out into the lawn areas surrounding the lake. The 100-year storm event floods an area of approximately 20 acres, including Duchon Field and the boathouse. A Hydrologic and Hydraulic study of Lake Ellyn was prepared by RHMG Consulting Engineers for the Village of Glen Ellyn and was completed in April 2012. The drainage area and flood statistics above were taken from that study. The purpose of the study was to assess the capacity of the Lake and to identify alternatives to prevent the Lake from overtopping the dam during the 100-year Lake Ellyn Park Lake Ellyn Watershed linden drainage area Lake Ellyn lyn lake road drainage area main inlet drainage area Village of Glen Ellyn Lake Ellyn watershed diagram 18 Glen Ellyn Park District
